It looks really good. Also awesome to see snippets of how you got to the final result.

My only critique is the (test tube)? At first, I thought they were holding a can of air freshener but then I thought it could be a test tube or a a vegetable like a leek. The aroma/mist makes me think it’s a test tube.

I was trying to think of a way to improve it (assuming it is a test tube). I think for sprite work, it needs to be over exaggerated. Maybe trying using a flask instead? The shape is a bit more iconic for the limited detail you can have in sprites.

Good job though!
